Textbook Question
Chapter 15, Problem 2TMW
Some strains of Staphylococcus aureus produce exfoliative toxin, a chemical that causes portions of the entire outer layer of the skin to be sloughed off in a disease called scalded skin syndrome. Given that cells of the outer layer are going to fall off anyway, why is this disease dangerous?

You develop a callus on the bottom of your hallux from a pair of ill-fitting shoes, and you feel the pain of an Onychocryptosis on the same hallux.
A treatment for Onychocryptosis is to remove the nail and apply a chemical such as phenol to the cells
the nail matrix, which kills the cells. What effect will killing the cells of the nail matrix have on the nail?
Is the answer below the correct answer to the question?

Histologic examination of the epidermis shows a layer of keratinocytes that have committed premature apoptosis (killed themselves before they normally would have died) and a lack of Langerhans cells in the affected region. Severe sunburns are followed several days later with non-bleeding blistering and peeling of large patches of skin. In the following weeks, the epidermis becomes thicker and darker (tan!). Hypothesize about which layers and/or sublayers of the skin are primarily affected; and about why the blistering, peeling, thickening, and darkening occurs. Be sure to explain your reasoning. This answer requires a logical hypothesis based on what we’ve learned about the specific microanatomy of the skin; it does not require “THE” correct answer.arrow_forward

Soon after arriving the ambulance medical technicians developed the same symptoms. All four of the individuals went to the emergency room where they were found to have rashes on various parts of the body in addition to their itch. The admitting nurse, who put her arm around one patient, also developed a rash and itch on her arm. A policeman who went to the apartment the following day and a trash collector at the building also developed itching and received emergency room treatment. In all cases, symptoms disappeared in 1-2 hours. An industrial hygienist went to the site in complete protective gear to look for possible chemical contamination. Visual inspection and screens for ionized organic vapors were negative, but he retrieved a bean pod. The botanical specimen was sent to Rutgers University, where the plant was…arrow_forward
- Watch the film from time stamp 12:19 minutes to 13:32 minutes. Pause when Dr. Jablonski says, “That is what melanin does.” In this segment of the film, Dr. Jablonski references a paper she had read about the connection between UV exposure and the essential nutrient folate (a B vitamin), which circulates throughout the body in the blood. The paper, published in 1978, describes how the serum (blood) folate concentrations differed between two groups of light-skinned people. You will now look at one of the figures from that paper. Figure 3. Folate Levels in Two Groups of People. In one group (“patients”), 10 individuals were exposed to intense UV light for at least 30–60 minutes once or twice a week for three months. Sixty-four individuals not receiving this treatment (“normal”) served as the control group. The difference between the two groups was statistically significant (p < 0.005).
